Swiss Cheese Cube - an Optical Illusion That Is Impossible to Print

All I wanted was to make something that looks cool, that was easy to create but was impossible to print. So here is the swiss cheese cube! The design is basic, a cube with 9 holes on each of its side.

Step 1: Can You Print It?

With a perfectly balanced printer that has good retraction, I think it would be possible to print this without support, but mine isn't capable of...

Step 2: If You Want to Try...

The STL files to print this bad boy (and a smaller 3x3 holes one) are on Thingiverse, try to do it and show me your failure (or succes)!
